Portable lock for toilet stalls

ABSTRACT

A device when installed between the physical gap between toilet partition panels provides a hook to hang personal items while the toilet is in use. The device also can be used to secure the toilet partition door to the toilet partition wall, preventing the door from being opened from the outside.

TECHNICAL FIELD

The present invention relates to a portable hook for use in toilet stalls. More specifically, the invention relates to a portable hook that can be used to hang personal items while the stall is in use. Still more specifically, the invention relates to a portable hook that can be used to hang personal items and secure the door of a toilet stall while the stall is in use.

BACKGROUND OF THE INVENTION

Toilet stalls are typically constructed of flat panels joined together by bracketry at certain points along their span. Where the edges of these panels come together, there is a physical gap that can be as much as a half of an inch. The invention disclosed within utilizes this physical gap to provide a hook for the convenience to the user of a toilet stall. In addition, the existing locks used in these stalls are not secure and often can be opened from either side of the door, either by hand or by common item like a coin. If the user of the toilet stall enters carrying a personal item (e.g. purse, garment bag, etc.) needing to be stored while the stall is in use, and if there is no hook located on the inside surfaces of the stall, the user will have to place their item(s) either on the floor or draped along the top of the toilet stall in peril of exposure to germs or theft. In addition, the existing locks provide no security from others opening the door from the outside.

SUMMARY OF THE INVENTION

What is presented is a portable hook that a user of a toilet stall can install to hang a personal item (e.g. purse or garment bag, etc.) while the stall is in use, and when installed between a door and a door jamb, secures the door preventing it from being opened from the outside. The device consists of two plates connected through their center with a threaded rod with a lever that draws the two plates closer together when rotated to a second position. When the lever is rotated to this second position, the plates move closer together compressing against the walls of the stall to a point where the device is held securely in place. The lever is of a shape that can be used as a hook for personal items after the plates are compressed together. The threaded rod is firmly attached to one plate, while the threaded rod passes through the other plate and attaches to an element of the lever.

The user enters the toilet stall and closes the door. This device is then inserted in the physical gap between the door and a fixed wall and slid down along this gap between the two, flat panels of the toilet stall. The lever is then rotated by the user, causing the two plates to come together while contacting with the door and door jamb, securing the door to the wall from the inside of the stall. The lever is shaped in such a way so that when it is rotated out, it presents a shape that locks the lever in place. The lever can then be used to securely hang personal items while the stall is in use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Turning to the drawing figures, in a preferred embodiment, (FIG. 1) an outside gasket [110] rests flush next to the outside plate [100] and said gasket is made of a compressible material. The center shaft [120] is securely attached to the center of the outside plate [100] with a fastener [180]. The center shaft [120] has at least one profile that is narrow enough to fit between the physical gap between the two flat panels of a toilet stall. The inside plate [200] has an inside gasket [210] of the same compliant material as the outside gasket [110]. The lever [300] has a tube nut [310] that rotates freely within the lever. FIG. 2 shows the threaded rod [130] threaded into the center shaft [120]. The threaded rod [130] also passes freely through the inside plate [200], inside gasket [210] and lever [300] and is secured to the tube nut [310] located within the lever [300] in such a way so that when the lever [300] rotates, the threaded rod [130] rotates to the same degree in the center shaft [120]. Rotating the lever on the threaded rod changes the gap made between the inside and outside plate to compensate for different door and wall thicknesses of a toilet stall. FIG. 3 shows the device with the lever [300] in the upright position, while FIG. 4 shows the device with the lever [300] in the rotated position. The distance between the plates is reduced [X is greater than Y] when the lever [300] is rotated. This is caused by a change in the profile the lever [300] presents to the inner plate [200] that moves the rotational axis of the tube nut [310] away from the inner plate, while the outer plate remains in place with respect to the tube nut given the physical connection between the outer plate and the center shaft, threaded rod and tube nut. FIG. 5 shows a typical toilet stall. From the inside of the stall and once the door has been closed, the device is inserted in the gap (FIG. 6) that exists between the door [500] and wall [600], with said door and said wall residing between the inside and outside gaskets, and the lever [300] and inside plate and inside gasket residing on the inside side of the toilet stall. This distance between the gaskets need to be far enough apart to be loose enough to allow the device to slide down the gap, if it is not correct, the knob can be rotated prior to being inserted to increase the gap between the plates until the plates and gaskets are far enough apart to allow the mechanism to be inserted between the walls of wall and door of a toilet stall. Once the device is in position within the toilet stall (FIG. 7), the lever [300] can be rotated with respect to the tube nut (FIG. 8), pushing the inside plate [200] closer to the outside plate [100], resulting in compressing both gaskets and firmly securing the device in place (FIG. 9). The lever can now be used to hang personal items from the device (FIG. 10) while it also secures the door, preventing the door from being opened from the outside.
